I’m on my way to my seat in a friends pub. Joining some locals to watch the F1 race in Mexico, but I want you to note this (updated):
AAPL,ig-platform-id Data <02002619>
AAPL,Gfx324 Data <01000000>
AAPL,GfxYTile Data <01000000> (Glitch Fix)
AAPL00,PanelPowerUp Data <30000000>
AAPL00,PanelPowerOn Data <19010000>
AAPL00,PanelPowerOff Data <11000000>
AAPL00,PanelPowerDown Data <3c000000>
AAPL00,PanelCycleDelay Data <fa000000>
I found this in the Skylake EG2 Graphics Driver (File GUID: 7AF77F94-4C38-4FF1-8CCD-3E084F2FFEC0) inside the MacBookPro13,1 firmware. You can find it yourself with the following steps:
1.) Download Build 16B2657 from the appStore
2.) Right-click on it and select Show Package Content
3.) Open InstallESD.dmg in Contents -> SharedSupport
4.) Go to Packages -> EFIPayloads
5.) Extract MBP131_0205_B02_LOCKED.fd
6.) Launch UEFITool and open the file and click on “Intel Image”.
7.) Search for “AAPL00” (Text) and click OK
8.) Double-click a result
9.) Right-click on the PE32 image section and select Hex view…
Edit: Now you know where to find them😉
This may be the chicken with the golden egg!
Update: Data added from MacBookPro13,1 (thanks to conradolpz).
device-colors Data <00020000 a09d9d00 00000000 00000000>
board-rev Data <14>
Update-2: Turns out that the AAPL,GfxYTile property is the one that we were looking for. Set this property, either from a (tiny) SSDT (see comments) or otherwise, and the graphic glitches should be solved.
Update-3: Property AAPL,Gfx324 is no longer there in the latest drivers.
